ため顆粒化が困難であった。BACKGROUND OF THE INVENTION Hitherto, there has been no method for granulating powdered calcium acetate. This is because calcium salts such as powdered calcium acetate have a property that once they harden under pressure in a hydrated state, they do not return to their original state, which makes it difficult to granulate them.

These many patients with chronic renal failure are unable to excrete phosphoric acid from their kidneys on their own, and the excretion of phosphoric acid by the artificial kidneys is also insufficient, resulting in low levels of phosphoric acid in the body. They often suffered from increased hyperphosphatemia. Conventionally, as a countermeasure for this hyperphosphatemia,
Aluminum hydroxide gel is taken as a phosphate adsorbent to prevent dietary phosphoric acid from being absorbed from the small intestine, but in this case, the aluminum in the aluminum hydroxide gel accumulates in the body, causing aluminum encephalopathy (aluminum encephalopathy). This caused dementia) and aluminum osteopathy (osteomalacia).

うとするものである。For this reason, the present inventors focused on using calcium acetate as a phosphoric acid adsorbent instead of aluminum hydroxide. When calcium acetate is used, the aforementioned problems with aluminum hydroxide do not occur. In general, calcium salts such as calcium acetate have small particle diameters and are highly cohesive powders in a hydrated state, which causes significant packaging errors when filling prescriptions, making dispensing very difficult. It's reality. In Japan, calcium acetate is only manufactured in powder form as a chemical product, and it is not possible to manufacture drugs in the form of tablets or capsules or to package them accurately, and it is difficult to take them as they are. Even if it were, there were problems such as it being difficult to take because it was in powder form. The present invention aims to provide a method for granulating powdered calcium acetate that solves the above problems.

There are two methods for granulating powder: dry granulation and wet granulation, both of which classify the active ingredient and add excipients (lactose, sucrose, sorbitol, starch, etc.) and disintegrants (starch, Usually, a binder (gelatin, gum arabic, glucose, sodium carboxymethylcellulose, etc.) is added and mixed. The present invention belongs to the wet granulation method and does not require any additives other than water, and due to the characteristics of the calcium salt, the granulated granules do not return to the original powder. of course,
It is possible to improve the dosing conditions by adding excipients, disintegrants, and flavoring agents as necessary.

As shown in the examples, for small-scale production, only the main ingredient, water, a sieve for granulating, a mortar for kneading the main ingredient, and a container for drying the granules are sufficient, and the key to granulation is the addition These are the quantitative range of water to be mixed, the temporal range of kneading, and its homogeneity. In addition, in the example,
The angle of repose (the angle between the free surface of the powder layer and the horizontal plane when depositing the powder), which is a measure of the fluidity of powder, changes from 60° to 37°, and the bulk density changes from 0.31 g/ml to 37°. 0.5
The granules were increased approximately 1.7 times to 2 g/ml, resulting in improved filling properties and very easy to handle granules. Here, the angle of repose is usually 4
0 to 30° is easy to handle, and if it is 50° or more, the fluidity decreases significantly. Furthermore, most of the added water was lost during the air-drying process, and it was confirmed using a thermal analyzer that the moisture content was almost the same as the original powder (approximately 10%).
